3.2.35. Start Stop Report
The command AT+GTSSR is used to detect the status of vehicle (Start or Stop status). When the
device detects that the vehicle is entering into start status, it will report event message
+RESP:GTSTR to the backend server. When the vehicle leaves the start status, and then enters
into stop status, it will report event message +RESP:GTSTP to the backend server.

 <Time to Stop>: After the vehicle enters into start status, if it rest again and keeps in that
status for this time long, the vehicle is considered to leave start status.
 <Time to Start>: If the vehicle is detected to be moving with ignition on for this time long, it
is considered to be in start status.
 <Start Speed>: The start speed threshold to determine whether the vehicle is start or not.
When the device is detected to be moving with ignition on by the built-in motion sensor, it
will start to check the speed from GPS. If the device speed stays greater than this <Start
Speed> longer than <Time to Start>, the vehicle is regarded to be start status. The event report
+RESP:GTSTR will be reported. Otherwise, if the device speed stays less than or equal with
this <Start Speed> longer than <Time to Stop>, the vehicle is regarded to quit start status. The
event report +RESP:GTSTP will be reported. If GPS fix abnormal more than 1 minutes,
only use the built-in motion sensor to detect the start / stop status and do not check the speed.
